Half a zebra. Zebra 1 asks, “Hey, do you think I’m white with black stripes or black with white stripes?”. Zebra 2 responds, “I don’t know, why don’t you go ask God?”. So, zebra 1 goes to God and asks him if he’s white with black stripes or black with white stripes, to which God responds, “You are what you are.”.
For a very long while biologists have sought to explain why zebras have their dramatic, black-and-white stripes. Many different explanations have been offered, none of which have gained general acceptance. Craig reviews some of these proposed explanations, and along the way gives us an appreciation of the stripes in their own terms. Maybe that
Zebra Characteristics. Zebras are generally 2.3 metres (8 feet) long, stand 1.25 – 1.5 metres (4 – 5 feet) at the shoulder and weigh around 300 kilograms (660 pounds), although some can grow to more than 410 kilograms (900 pounds). Zebras have excellent hearing and eyesight and are capable of running at speeds of up to 40 miles per hour.
In contrast, observational studies of zebras fleeing do not support a confusion effect , stripes can only be resolved by predators at close distances undermining camouflage ideas (Melin et al., 2016) and experiments with striped objects find no support for a cooling effect (Horváth et al., 2018). Nonetheless, the mechanism by which stripes
Zebras with golden coats, black splotches, and light-colored stripes have been photographed in the past. As recent as 2019, scientists discovered a polka-dotted zebra youngling with white spots in
In fact, the fact that zebras have stripes at all is still sort of a surprise. In African landscapes that are green, brown, blue, and yellow, painting your butt with sharp streaks of black and

Read on to discover these and other bizarre facts about zebras. 1. A ZEBRA’S COAT IS A GIANT BAR CODE—AND WE CAN SCAN IT. Getty Images. Every zebra has a unique pattern of stripes. And
There had been four main hypotheses to explain why zebras have their stripes: camouflage to avoid large predators. a social function like individual recognition. thermoregulation, with stripes
There are a number of adaptive hypotheses for the existence of striping in zebras [ 13 ], including predation evasion [ 14, 15 ], thermoregulation [ 14 ], social cohesion [ 16] and avoidance of biting flies [ 17 ]. In this paper we put the predation, thermoregulation and biting fly hypotheses to a spatially explicit empirical test by modelling
